Brief History

On January 21, 2017, the Women’s March on NYC coordinated the assembly of an estimated 750,000 people to demonstrate public support for women’s rights. Dozens of unique grassroots organizations joined this event under a shared vision that all humans are equal and deserve equal treatment. We are and have always been 100% independent from Women’s March, Inc.

Following this event, 120,000 individuals registered with Women’s March on NYC to continue receiving information about women’s rights and future events. An additional 33,000 registered to follow Women’s March on NYC on Facebook, Twitter, and Instagram.

Because of this public demand for continued information, education, and events that support human rights, the Women’s March on NYC created the nonprofit Women’s March Alliance (WMA) whose mission is to raise women’s voices through education and activism. We will equip our communities with the tools necessary to demand change and defend our rights.
